DISPEN SING APPARATUS.

Specification of Letters Patent.

Patented Dec. 17, 1907.

Application tiled April 25| 1906. Serial No. 313.618.

T o all whom. it may concern:

Be it knownl that I, GL'sTAvE J. HOLL, a citizen of the United States,residing at Knoxville, in the county of Knox and State of Tennessee,have invented a new and useful improvement in Dispensing Apparatus, ofwhich the following is a specification, reference being had to theaccompanying drawing.

My improvement relates particularly to mechanism for dispensing liquidsand also solids when the latter are in the form of powder or granules orpellets or similar small masses adapted to run or ilow by gravity.

One of the chief usi-s to which my apparatus is to be put is thedispensing of soap and similar cleansing materials, over or adjacent toa wash-bowl, the apparatus being adapted to discharge small measuredquantities fron a larger quantity contained in a reservoir, sai:reservoir being substantially hermetic` ally sealed in order thatevaporation may be avoided and in order that the soap if placed intosaid reservoir in sterilized condition may so remain.

In the accompanying drawings, Figure 1 is a fragmentary side elevationshowing my improved apparatus applied to a tloor, wall, and wash-stand;Fig. 2 1s an upright section of the upper nirtion of the apparatus shownin Fig. 1, said section being from front to rear on the indirect dottedline, 2 2, of F ig. 4; Fig. 3 is a fragmentary view looking at the frontof the apparatus, the measuring mechanism being inverted for the removaland rciilling of the reservoir; Fig. 4 is a horizontal section on theline, L1 4, of Fig., l; Fig. 5 is a. detail view of a portion of thebell-crank and the horizontal connecting rod; Fig. (i is a front view ofthe wall bracket; Fig. 7 is an upright section on the line 7 7 of Fig.1, looking in the direction of the arrow.

Referring to said drawings, A is the floor, and B is an upright wall oila room, and C is a wash-bowl attached to said wall.

At a short dist-ancov above the wasn-bowl is a wall bracket, 1, securedimmovably to the wall, B, in any suitable manner, as by means of boltsor screws, 2, extending through said bracket into the wall. To the outerportion oi' said bracket is applied a circular or disk form head, Si,having an approximately centra-l aperture, 4, and 1n its upper edge anotch, 5. To the front face of said head is applied a circular plate, 6,having a rearward-directed circumferential iiange, 7,

fitting closely around the circumferential edge of the head, '3, therear face of said ilange being approximately flush with the rear face ofsaid head. applied to the rear face of said ilangc by means of screws,9, and extended over a portion of the rear face of said head. T hus thecircular plate, 6, is held rotatably upon said Binding plates, S, are

head, the rotation being on a horizontal axis.

The plate, (i, has anaperture, 6, located opposite the aperture, 4, inthe head,

A notch, 5, is formed in theinne" face of the. llange, 7, opposite thenotch, 5; and a spring arm, 7, has one end resting in said 70 When saidfree to rotate.

From. the upper portion of the circular plate, 6, a reservoir-supportingmember, 10, extends hln'izontally-orward. Said plate and said member arepreferably integral and the plate may be considered a part of -themember. In the forward portion of said member, 10, is an uprightaperture, 11, through which project; a bolt, i2. Loosely surroundmg saidbolt below the bracket is a.

measuring cylinder, 13, the lower face of said Y bracket heilig dressedsmooth and even to make a close tit with the upper face of saidcylinder. Said cylinder is shown as having four upright chambers, 14,each extending entirely through thel cylinder, 13. Below said cylinder,said boli, 12, is surrounded by a bottom plate, E5, which has a downwarddirected sleeve, 16, extending through an arm, 17, which arm alsosurrounds said bolt. And said plate, 15, has a` notched lateralextension, 15, which bears against the circular plate, 6, to preventrotation of said plate, 15, on the bolt, 12. Inunediately below saidsleeve said bolt is surrounded by a washer, 18, adapted to bear againstsaid sleeve, and below said washer an expanding coiled spring, 1S),surrounds said bolt and bears against said washer; and below said springsaid bolt is surrounded by another washer, 20; and below the lastmentioned washer, said bolt is surrounded by a nu' 21, supporting saidlast mentioned washer. By means of said nut.

i l t Salti W or. Ttj opressed upward so that the bottom plate, 15, ismade to bear closely against the lower face of said measuring cylinder.The. meeting faces of said cylinder and said bottom plate are to beformed smooth and even so that liquid will not pass between them.

At the front of the bottom plate, 15, is a depending spout, 15b, withwhich the chambers, 14, may, one at a time, register. Below the mouth ofsaid spout is a guard, 15. Said guard may be. integral with the spout.1t docsnot extend into the path o the discharge from said mouth. Thusthe material discharged does not touch said guard and does not becomecontaminated by any in aterial adhering to the guard. The purpose of theguard is to keep thel hands of persons who wash from bearing against andcontaminating the mout-h of' the spout.

At the rear of the bolt, 12, an interior-lythrcaded nipple, 22, extendsupward; and a passage, 23, extends through the bracketfroni the interiorof said nipple downward into proper position to conununicate with thechambers, 14, of the measuring cylinder, 13.

A l. ott-leform reservoir, 24, having an exteriorly-threaded neck, 25,is threaded into said nipple, 22, in the inverted position.

f Upon the perimeter of the measuring c vlinder are four equi-distantratchet teeth, 26, Aadapted to be engaged by a pawl, 27. Said pawl ishinged upon the arm, 1T, by means of an upright screw, 2S. An expandingspring, 29, bears against the arm, 17, and an. extension, 30, of thepawl, 27, and causes said awl to normally bear against said measuringcylinder.

To the lower portion of the bracket, 1, is hinged an upright bell-crank,31, and the upper arm of said bell-crank terminates in a ring, 32, andsaid ring is coupled with the ring, 33, of a horizontal connecting rodor bar, 34, which extends through the aperture, 4, in the head, 3, andthe aperture, o, in the circular plate, 6, and is hinged to the upperface of the arm, 17, by an upright screw, $5.5.

From the lower arm of the belhcrank, 31, a connecting rod, 36, extendsdownward and has its lower end coupled to a treadle, 37, which treadlemay be supported in an)y suitable manner, as bv being hinged to a chair,

38, at 39, the relation of the parts being such as that the pedal end ofsaid treadle will be in its elevated position while the pawl, 27, is atthe forward limit of its range of movement.

The reaimost chamber of the measuring cylinder, 13, becomes iilled bythe flow of material downward from the reservoir through the aperture,11. Each movement of the trcadle imparts to the measuring cylinder aquarter rotation so that the irst movement of the mda] moves therearmost chamber of the c inde-r to one of the lateral positions, and tie next movement of the treadle brings said aperture to the iront `so asto register with the discharge spout. The

vbottom-plate covers all ol the. lower face of the cylinder, exceptingtbe portieri at the spout, so that the chambers of the cylinder areprevented from discharging until they register with thc spout.. Thus,when the amparatus is in practical use, each operation of the treadlecauses the contents of one chamber of the cylinder to discharge bygravier through the spout.

Yt'hen the apparatus is being manufactured, the meeting faces. of thereservoirsupporting member, the measuring cylinder, and the bottom plateare made. smooth and even' so that when they are pressed together, theywill Vlit so closely as to prevent thc passage of air. and springwhereby said member, cylinder, and bottom plate are held to each other,any wear of said meeting laces' may be taken up so as to maintain theclose meeting of said faces. In fact this construction is adapted todevelop a closer lit ol' said faces by wear; for the rotation ol saidcylinder has a grinding ctie; t adapted to causo said meeting faces tocoliform more closely to each other, and after such grinding, saidspring and bolt continue to press said member, cylinder, and bottomplate against each other.

dien the material stored in the reservoir becomes exhausted, the l`reeend of the .spring arm, 7, is pressed downward, whereby thereservoinsupporting member is rendered free to rotate upon the head, 3,of the bracket, 1, until the reservoir is in the approximately invertedposition shown in F ig. 3. Then the reservoir is nnserewed from thenipple, 22, and refilled and again screwed into said nipple. 'lhcn saidsupporting member is rotated in the reverse direction until it hasassumed its normal position, whereupon the spring arm or key, 7, springsoutward into the not-ch, 5, whereby said member is again locked.

When the material is being discharged from the chamber registering withthe spout, the place of said material in said chamber is taken by airrising through the spoilt, so that when said chamber moves forward andagain becomes covered by the bottom plate it is full of air. And when itagain assumes the rearmost position, so as to register with tlf-eaperture., 11, the air contained by said chamber rises into thereservoir as the material in the reservoir descends. In this wav, theforming of a vacuum in said reservoir is avoided.
